yj999 to d300? mixed info

I've been getting mixed info on this. I'm thinking about putting a tf999 from a 90 yj with a 4.2 into my 81 cj8 with a 4.2, t4, and d300. I thought the d300 will bolt right up to the yj tf999 but I've heard differently from some people. Is there any truth to this? I know it has the 23 spline output and the correct bolt pattern. Some say a spacer is needed like with a ax15. Is this transmission any different than the tf999 used in cjs?

I've got a TF999 and a dana300 in my 80 CJ7, but that's what came in it.

Re: yj999 to d300? mixed info

My 86 cj7 came with a TF999 and dana 300 from the factory. I am not sure if the bolt pattern was changed when they started using the NP transfer cases in the wranglers or not...and isn't your wrangler driver's side drop from the t case? the dana 300 is passenger side...this would mean your front pumpkin would be on the wrong side....hope this helps

Bolts right up. I have a '95 4.0/ '94 32RH (YJ version of a T999)/ '83 D300 combo in my Scrambler.
